note 86424 added to function.floor

marc at moblaster's rounding technique for handling financial truncation fails for 0.0, and probably has unintended consequences for values less than 0. Something like this should do the trick: function truncateMoneyFloat($amount) { if ($amount > 0.005) return round($amount - 0.005,2); elseif ($amount < -0.005) return round($amount + 0.005,2); else return 0.0; } However, +1 billion for jolyon at mways' comment regarding abandoning floats entirely when processing financial data. Create a money class and track the value internally with an integer. Provide methods to scale by float values where the rounding behavior can be controlled by an explicit policy variable. ---- Server IP: 209.41.74.194 Probable Submitter: 24.22.117.179 ---- Manual Page -- http://www.php.net/manual/en/function.floor.php Edit -- https://master.php.net/note/edit/86424 Del: integrated -- https://master.php.net/note/delete/86424/integrated Del: useless -- https://master.php.net/note/delete/86424/useless Del: bad code -- https://master.php.net/note/delete/86424/bad+code Del: spam -- https://master.php.net/note/delete/86424/spam Del: non-english -- https://master.php.net/note/delete/86424/non-english Del: in docs -- https://master.php.net/note/delete/86424/in+docs Del: other reasons-- https://master.php.net/note/delete/86424 Reject -- https://master.php.net/note/reject/86424 Search -- https://master.php.net/manage/user-notes.php
